Opinion

ENTANGLED MEDIA, LLC, Case No. 23-cv-03264-PCP

Plaintiff, ORDER DENYING MOTION TO v. DISMISS

Defendant.

Plaintiff Entangled Media, LLC alleges that defendant Dropbox Inc. infringes two patents related to cloud-based file systems. Dropbox moves to dismiss Entangled Media’s first amended complaint, contending that the claims of the asserted patents are not patent-eligible under 35 U.S.C. § 101. For the reasons that follow, the Court denies Dropbox’s motion to dismiss. The Court accepts the following facts from Entangled Media’s complaint as true for the purposes of Dropbox’s Rule 12(b)(6) motion to dismiss. Entangled Media owns U.S. Patent Nos. 8,296,338 (“the ’338 Patent”) and 8,484,260 (“the ’260 Patent”) (collectively, the asserted patents). The ’338 patent was issued on October 23, 2012, and is titled “Method for a Cloud-Based Meta-File System to Virtually Unify Remote and Local Files Across a Range of Devices’ Local File Systems.” Dkt. No. 19-1, ’338 Patent, at 2. The ’260 Patent is a divisional application of the ’338 Patent. Dkt. No. 19-2, ’260 Patent, at 2. The ’260 Patent was issued on July 9, 2013, and is titled “Method for Cloud-Based Meta-File System to Virtually Unify Remote and Local Files Across a Range of Devices’ Local File System.” Id. The patents share substantially the same specification. with a cloud-based file system that is shared among devices and integrated into the device operating system so as to unify the representation of files across devices for availability of and access to data across multiple devices a user might own.” ’338 Patent at 1:20–25.1 The invention seeks to overcome the shortcomings of prior art methods for data synchronization that typically relied on either “locally installed software for file replication across devices” or “online backup/storage based file replication across devices.” Id. at 1:28–30. These prior methods required large amounts of storage, id. at 1:50–55, and existing methods for increasing storage capacity were expensive and involved “third-party on-line storage or device storage upgrades,” id. at 1:55–58. Further, these methods required that “the data on separate devices [be] kept separated when synchronized-local data is stored in a set of locations within the operating system’s native file system (e.g., ‘My Documents’, ‘My Pictures’, etc.), while remote data on other devices or other online services [be] kept in a new location such as a new directory/folder or secondary location (e.g., removable hard drive) mounted on the device.” Id. at 1:59–65. These methods also demanded a “high-degree of user involvement for their operation,” requiring users to “designate certain files and/or directories for synchronization or backup” and “consciously store content to be synced or backed-up in those locations.” Id. at 1:65–2:2. Unlike the prior art, Entangled Media’s invention does not require “physical data replication across multiple devices.” Id. at 2:18–20. Instead, it “creates a virtual representation of data on all of the devices using metadata indexing” that “allows for otherwise impossible amounts of data to be virtually stored on each device” without requiring that the files themselves be stored on all devices. Id. at 2:20–28. The solution “does not require data to be stored on a provider server, but instead stores only light-weight metadata … online.” Id. 2:29–32. It “establishes the ability for user devices to be aware of one another and communicate directly when data is requested,” id. at 2:32–34, and “can also incorporate files stored in an online service account, such as a photo account or video account (exemplary—YouTube.com or Picasa.com),” id. at 2:35–37. The claims of the ’260 Patent disclose a method for improving computer functionality by allowing for the transfer of physical files located on different devices using a peer-to-peer connection. See ’260 Patent, at 11:25–52. While the claims of the ’338 Patent disclose a “process for establishing a singular file system across multiple devices,” ’338 Patent at 11:22–23, the ’260 Patent discloses a “process for operating on files located on multiple devices using a singular file system” to facilitate the transfer of a file from the first device to the second device through a brokered peer-to-peer connection, ’260 Patent at 11:54–52. The latter process “allows the devices to communicate and share their data and resources directly and negates the need for a server, which eliminates additional costs and complex set-ups” and “is typically faster than transferring over other types of network connections.” First Amended Complaint (FAC) ¶ 39. Claim 1 of the ’338 Patent recites: A process for establishing a singular file system across multiple devices comprising: receiving user information to open an account for establishing a singular file system across multiple devices via a web-based system that includes at least one server; installing an individual software client on each of the multiple devices via the web- based system; accepting registration of multiple devices via the web based system; Scanning each of the multiple devices by each of the individual software clients to inventory data on each of the multiple devices and create a meta-index of the files for the inventoried data; providing by the individual software clients via the multiple devices individual meta-indices of the inventoried data for each of the multiple devices to the at least one server; integrating by the at least one server the individual meta indices to create a single master meta- index; providing by the at least one server the single master meta index and meta-indices for each of the other multiple devices to each of the multiple devices via the individual software clients; integrating metadata from the meta-indices of each of the other multiple devices into a local file system of each of the multiple devices to generate virtual files stored in the same locations as local files of the local file system, the virtual files indistinguishable from the local files by the local file system at each of the multiple devices; and continually updating the single master meta-index on the at least one server and each of the multiple devices in response to changes to the data indexed thereon, wherein the individual software clients facilitate storage of the data within each of the multiple devices in accordance with the single meta-data index by modifying file systems of each of the multiple devices to include virtual files for data from the single meta- data index that is not local to a multiple device. Claim 1 of the ’260 Patent recites: A process for operating on files located on multiple devices using a singular file system comprising: accepting a request to operate on a file at a first device, wherein the file is selected from the singular file system on the first device: modifying the singular file system on the first device to make local files and virtual files appear indistinguishable to the singular file system, the local files and virtual files sharing a same location on the first device; intercepting the request by a software client on the first device; determining by the software client if the file is physically located on the first device or if the file is a virtual file of a corresponding file physically stored on a second device by reviewing file metadata, wherein a visual representation of the singular file system on the first device is identical to a visual representation of the singular file system on the second device; and if the file is the virtual file of the corresponding file physically located on the second device, requesting by the software client on the first device that a peer-to-peer connection be brokered by a server-based web service between the first device and the second device; if the peer-to-peer connection is brokered, transfer
